What Sunny Windowsill asks of you
This is where Catdoku teaches itself. The first boards fall to the last free square alone, and each new board size brings one more idea with it.
Start with the smallest patch on the board: a patch of two or three squares has the fewest places to hide its cat. After every cat, cross out its row, its column, its patch and the four corner squares around it.
Techniques you will need
- Last free squareA row, column or patch is down to one square that can still hold a cat, so the cat goes there.Needed on 100% of Sunny Windowsill boards, about 7.4 times per board.
- Patch in a lineEvery free square of a patch sits in one row or column, so that line belongs to the patch and the rest of it can be crossed out. It works the other way round too.Needed on 90% of Sunny Windowsill boards, about 2.8 times per board.
- Dead-end squarePicture a cat on a square. If it would cross out every last spot in some row, column or patch, that square can never hold a cat.Needed on 73% of Sunny Windowsill boards, about 3.6 times per board.
- Counting trickWhen two patches fit entirely inside the same two rows (or three inside three, and so on), those rows are theirs. Every other square in them can be crossed out.Needed on 19% of Sunny Windowsill boards, about 0.3 times per board.
